Further testing shows the floor doesn't work. Back to the tubing crotch.

BTW, I tried and rejected the yoke mount. It places the display to
close to my eyes compared to the rest of the panel (aging eyes). I
fabricated a bracket to hang it from the panel over the flap handle.
May be OK but taking a trip this weekend to test.

This is my first 'portable'. I am not happy with the wires and location
options. Definitely a compromise over panel mounts, but I guess that's
no surprise.

Well, it definitely can sit up there in the tubing crotch, well clear of
cables, etc. But it definitely won't be removeable.

I'm now looking at just laying it on the floor in the baggage area and
stringing the cable along the floor. The extension plug will end up
right under my seat. The question I haven't answered yet is whether it
will receive well from there but I think it might given the extensive
composite construction on the Maule (composite = tubing, sheet metal,
fabric, and glass :-) )

It seems to work just fine up there thru fabric and insulation -
perfect! I can get as far away from the compass as the cable allows.
Looks like the magnet naturally finds a crotch a in the tubing to
magnetize itself too.

Great! Just keep it away from the aileron cables.
